Deactivate deco gas calculation option:
In the previous version had the option to consider a deco gas i the calculation or not. Reason for this was to have the automatic gas suggestion available while the deco calculation is still based on the current gas.
This might cause a critical situation in case the diver is not sure if the option is active or not => In the new version the TTS / deco is always calculated considering all deco gases.
